In today's cloud computing environment, strong security is essential for protecting applications, resources and business data.

This is where AWS security tools become valuable. From detecting suspicious activity to managing access and identifying vulnerabilities, each tool serves a specific purpose. Let's explore the tools that can help strengthen your organisation's cloud security.

Top 12 AWS Security Tools

AWS environments can be protected using a combination of AWS security services and third-party tools. These tools support different security requirements, from identifying threats and managing vulnerabilities to protecting sensitive information. Here are 12 AWS security tools and their key features:

1) AWS Security Hub

AWS Security Hub is a unified cloud security service that helps organisations identify, prioritise and respond to critical security risks across their AWS environments. By correlating findings from different sources, Security Hub helps security teams understand risks that may not be obvious when individual alerts are examined separately.

AWS Security Hub CSPM focuses specifically on assessing cloud security posture through security best-practice checks and compliance-related controls. These complementary capabilities help organisations identify misconfigurations, understand exposures and prioritise remediation activities.

Features:

a) Correlates security findings from supported AWS security services.

b) Provides risk prioritisation and visibility across AWS accounts and resources.

c) Supports automated security response workflows through configurable rules and integrations.

Trainer Insight

Not every security finding represents the same level of risk. Consider resource exposure, business importance and related vulnerabilities rather than prioritising alerts by severity alone. This helps security teams focus on issues that could have the greatest impact.

2) Amazon GuardDuty

Amazon GuardDuty is a threat detection service that continuously analyses supported AWS data sources to identify potentially malicious or unauthorised activity. It uses threat intelligence, machine learning and anomaly detection techniques to identify suspicious behaviour. 

Depending on the protection features enabled, GuardDuty can help detect threats affecting AWS accounts, workloads and supported services. For example, it may identify unusual API activity, suspicious network communications or signs of compromised resources. These findings help security teams investigate potential threats and take appropriate action.

Features:

a) Continuously analyses supported security signals for suspicious activity.

b) Uses threat intelligence and behavioural analysis to identify potential threats.

c) Generates security findings that can support investigation and automated response workflows.

3) AWS Identity and Access Management (IAM)

AWS Identity and Access Management (IAM) helps organisations securely control access to AWS services and resources. It allows administrators to define permissions through policies and manage how identities access AWS resources. IAM roles can provide temporary security credentials, reducing the need to distribute long-term access keys.

For example, an organisation can use IAM to allow a development application to access a specific Amazon S3 bucket without granting unnecessary permissions to other resources. IAM plays an important role in implementing least-privilege access and reducing the risks associated with excessive permissions.

Features:

a) Manages permissions for users, roles and supported AWS resources.

b) Supports fine-grained access control through IAM policies.

c) Enables temporary credentials through IAM roles.

Pro Tip

Avoid granting broad permissions when creating IAM policies. Provide only the access required for specific tasks, review unused permissions regularly and prefer temporary credentials wherever practical. This helps reduce the potential impact of compromised identities.  

4) Amazon Inspector

Amazon Inspector is an automated vulnerability management service that helps organisations identify security weaknesses in supported AWS workloads. It continuously scans supported Amazon EC2 instances, Amazon Elastic Container Registry (Amazon ECR) container images and AWS Lambda functions for software vulnerabilities. 

It also identifies network reachability issues affecting supported Amazon EC2 instances. When a vulnerability is identified, Amazon Inspector generates findings containing relevant information, including severity and remediation details. This helps security teams prioritise vulnerabilities and address weaknesses before they can be exploited.

Features:

a) Continuously scans supported AWS workloads for software vulnerabilities.

b) Identifies network reachability issues affecting supported Amazon EC2 instances.

c) Provides prioritised findings and remediation information.

5) AWS Config

AWS Config is a service that helps organisations assess and audit the configurations of their AWS resources. It records supported resource configurations and changes, allowing security teams to review how infrastructure settings evolve over time.

AWS Config rules can also evaluate resource configurations against specified requirements or desired settings. This helps organisations identify configuration issues and assess compliance with internal security policies. For example, AWS Config can help identify Amazon S3 buckets that do not meet defined configuration requirements.

Features:

a) Records supported resource configurations and changes.

b) Evaluates configurations using managed or custom AWS Config rules.

c) Supports compliance monitoring and automated remediation through integrations.

6) AWS CloudTrail

AWS CloudTrail helps organisations record and review activity across their AWS accounts and supported services. It captures information about AWS API activity, including actions performed through the AWS Management Console, AWS Command Line Interface (AWS CLI), SDKs and other supported AWS services.

CloudTrail provides an event history for recent management activity and supports additional logging through trails and event data stores. For example, security teams can use CloudTrail records to investigate changes to IAM permissions or identify actions taken during a potential security incident.

Features:

a) Records supported AWS account and API activity.

b) Supports auditing, security investigations and governance requirements.

c) Provides logging and event analysis capabilities for monitoring account activity.

7) AWS WAF

AWS WAF is a web application firewall that helps protect supported web applications and APIs from malicious HTTP and HTTPS requests. It allows organisations to create rules that inspect incoming web traffic and block or challenge requests that match specified conditions.

AWS WAF can help reduce exposure to common web attacks, including certain SQL injection and cross-site scripting attempts. For example, an organisation can configure AWS WAF to filter suspicious requests directed towards an application delivered through Amazon CloudFront.

Features:

a) Filters web requests using configurable security rules.
